Test Details
Methodology
Polymerase Chain Reaction (PCR)
Result Turnaround Time
3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
The Mumps Virus PCR test is used to confirm mumps infection in patients with compatible symptoms of mumps infection, including parotitis. Samples for Mumps Virus PCR should be collected as soon as practical after symptom onset.
Limitations
A negative test does not rule out infection with mumps virus. Results should be interpreted in conjunction with clinical findings, and if required, serological testing. Specimens should be collected as soon as possible after the onset of symptoms to maximize the sensitivity of mumps virus detection. Improperly collected samples may result in false negative results. PCR assays may be impacted by viral variants and may result in reduced sensitivity or false negative results.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Specimen Requirements
Specimen
Buccal swab
Volume
One swab
Minimum Volume
One swab
Container
Viral Transport Media (VTM) or Universal Transport Media (UTM)
Collection Instructions
Collect a buccal swab specimen by massaging the parotid gland for 30 seconds. Using a synthetic swab, collect the sample by sweeping the swab between the cheek and gum from the upper molar to the lower molar for 10-15 seconds, while turning the swab. Sweep both sides with a single swab and place the swab into the VTM or UTM tube. Ensure the VTM or UTM tube is capped tightly to avoid leakage.
Stability Requirements
Temperature | Period |
|---|---|
Refrigerated | 7 days |
Frozen | 14 days |
Storage Instructions
Refrigerated or frozen
Causes for Rejection
Improperly submitted specimens including specimens not received in an approved VTM/UTM; swabs received in Liquid Amies (E-Swabs) or other bacterial swabs; specimens received without a swab; grossly leaking specimens and specimens received outside the stated stability
